Drivers using msm_iommu_register_notify currently don't link when
CONFIG_MSM_IOMMU_V1=n. We may want to implement the notifier for
msm_iommu_v0 in the future, but until then provide a stub to allow
successful compilation and linking of driver using
msm_iommu_register_notify.

There are some events that IOMMU client drivers might like to be
notified about. Add a notifier chain for this purpose. Currently the
only supported event is TLB sync timeout.

ASID conflict between 2 CBs can lead to some odd behavior
of SMMU. Present way of ASID allotment can conflict with
the ASID being used by secure world. Use the CB number
as ASID. That will ensure that we will not use any other
ASID which secure world may think of using it.

For some of the smmus's the number of unique stream
ids is more than the number of Stream Mapping
Table entries. The mask field of the SMRn register
needs to updated to handle the correct mapping
behaviour.

Within SMMUv2, different implementation have
different Software interface. Support IOMMU
driver to be compatible with MMU-500.

Present logic of enabling aggregated CB interrupts works only
for non-secure SMMUs. Improvise that logic to enable interrupts
for secure SMMUs also.

Header files are no longer allowed in the directory
arch/arm/mach-msm/include/mach/ .
Move the iommu related header files to a more suitable place.
